Optimizing post-surgical outcomes: unveiling the importance of patient-reported outcomes with insights from the schulthess local shoulder arthroplasty registry

From March 2006 to December 2023, the SAR included 98% of eligible operations. A total of 2301 patients were recruited, accounting for 3576 operations and 14,487 person-years of follow-up. At baseline, the mean age was 71 (range: 20-95), with 65% being female patients. The most prevalent indication was cuff tear arthropathy (46%), and the mean preoperative Constant Score was (31 ± 15). Notably, functional recovery peaked at 12 months postoperatively, displaying no clinically significant deterioration during the initial ten follow-up years in the overall cohort (including both primary arthroplasty and revisions). The registry has been instrumental in addressing various clinical and methodological inquiries, focusing particularly on comparing different implant configurations and surgical techniques to optimize functional recovery. Additionally, SAR data played a pivotal role in substantiating the clinical significance and reliability of radiological monitoring for cortical bone resorption, scapular notching, and glenoid component loosening.
